challenge, and in a heroic and valiant combat he killed 'Amr ibn 'Abd Wud.
The death of 'Amr and the lengthy ineffectiveness of the siege especially the tactics deployed by the Prophet made the Jews retire from the combat. The weather, too, became severely cold and a violent wind started blowing so that it shook the tents of the Quraysh army violently, extinguished their fires and caused their horses and camels to flee to the desert, and thus complete chaos and disorder reigned over the whole army of the enemy.
Abu Sufyan who was furious with this state of affairs, summoned the army commanders for consultation and said to them: "0 men of Quraysh! I swear to your god that you are in a land where one cannot live or stay longer. Our horses and camels have run away. The Jews of Banu Qurayzah who were our allies have abandoned their pact and left us. Moreover, as you see we are confronted with cold and bad weather, which has even put out our fires and has left no tent standing. Therefore, I think we had better return. I am ready to move back."
In the same dark night the large army of the Quraysh and their allies departed for Mecca and their own tribes.(48) Abu Sufyan was in such a hurry to flee that he forgot to untie the foot-fetters of his camel and leapt on its back to move
Thus the big battle of al-Khandaq (or al-Ahzab) ended without any result for Abu Sufyan, and the big army of the infidels despite their large number failed to do anything against Islam, the religion of God.

Feeling of weakness
and proposal of peace

O people! I have concluded a pact between the Quraysh and the Muslims.
Abu Sufyan

The weakness of the parties opposed to Islam, despite their greater number greatly asserted the power, dignity and glory of Islamic front, and the Muslims were now recognized as a power
